526 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



In a supplement to my memoir on the crinoids collected by the Hamburg South- 

 west Australian Expedition, which was published in 1913, I changed the name Dichro- 

 metra U n, ra to D. {luges, added Port Molle to the list of known localities, and figured 

 the specimen with 7 rays and 57 arms. Port Molle was added to the list of localities 

 by error. This is the locality for Bell's Antedon reginae, which at the time was con- 

 sidered to be synonymous with gyges instead of with Dichrometra articidata. 



In a revision of the family Mariametridae published in 1913 I transferred gyges 

 and tenera to the new genus Lamprometra. 



In a paper on the crinoids of the British Museum published in 1913, under the 

 beading Lamprometra gyges, I gave notes on the type specimen of Bell's Antedon gyges 

 and recorded specimens from Port Essington and from north of Cape Hillsboro' that 

 were labeled Antedon articulata. Hartlaub's Antedon tenera was placed in the 

 synonymy of Lamprometra gyges. 



Dr. Hubert Lyman Clark in 1915 recorded a specimen of Dichrometra tenera 

 from Ceylon. This is herein placed under Lamprometra palmata palmata, but it is 

 only fair to Dr. Clark to say that it might equally well be placed under L. p. gyges. 



Dr. Robert Hartmeyer in 1916 published a note saying that the specimens of 

 Dichrometra tenera from Western Australia had been given the catalog number 5965 

 in the Berlin Museum, and that the author had later redetermined these as D. gyges. 



In my report on the unstalked crinoids of the Siboga expedition I included gyges 

 in my key to the species of Lamprometra, giving Antedon tenera Hartlaub as a synonym 

 of gyges in a footnote. The specimen recorded as L. protectus (=palmata) from sta- 

 tion 209 is herein considered as representing L. p. gyges. 



In his memoir on the echinoderm fauna of Torres Strait published in 1921, Dr. 

 H. L. Clark said that he had found only one comatulid at Mer that could be referred 

 to Lamprometra gyges and mentioned other specimens that had been collected by Frank 

 A. Potts on a reef north of Mabuag, Torres Strait, in November 1913, which I had 

 identified as gyges. He gave notes on the specimen from Mer and figured it in colors, 

 giving photographs of one of the specimens from Mabuag. 



In 1923 Dr. Clark recorded and gave notes on two specimens of Lamprometra 

 gyges from Wooded Isle, Abrolhos Islands (or Houtman's Rocks), Western Australia. 



Frank A. McNeill and A. A. Livingstone in 1926 recorded and gave notes on a 

 specimen of Lamprometra gyges from Port Darwin. 



In 1929 I recorded one specimen from Hermit Island, northwestern Australia, 

 and two from Australia that had been sent me for determination by the British 

 Museum. 



Dr. H. L. Clark in 1932 recorded a single specimen from the Great Barrier Reef 

 Expedition, 1928-1929, which bore the labels "G. B. R. E. General Survey, 24/4/29, 

 A4" and "Dichrometra tenera (Hartlaub), 1 spec. H. L. Clark, St. XVII." He said 

 that this is apparently a specimen seen by him in Sydney in November 1929 and given 

 Hartlaub's name, which is a synonym of gyges. He added that obviously one of the 

 labels is wrong as to locality, and he believed the specimen came from A4. 



In 1938 Dr. H. L. Clark recorded and gave notes on 24 specimens that he had 

 collected in 1929 and 1932 at Darwin, Broome, and False Cape Bossut, recording them 

 as Lamprometra gyges.
